After pregnancy
Pregnant mommy will face countless firsts in her life
For example, maternity examinations under various names
Especially for new moms
I don't know how to check selectively
Anyway
Orthodontic examination is a top priority
Where, NT examination
As the first line of defense for fetal treasure health
Pregnant mommy must not be easily missed
01
What is NT checking
NT is an abbreviation for translucent membrane of the fetal neck, which is a translucent protein membrane that flows around the back of the fetal neck during 10-13 weeks of pregnancy. Its thickness is positively correlated with fetal DS defects and can be measured by ultrasound imaging.
NT derating refers to the thickness of fluid accumulation in the subcutaneous tissue at the back of the fetus's neck. By measuring the thickness of the transparent layer of the neck by ultrasound, it is possible to screen Down children and fetuses with congenital heart disease, and timely intervention and treatment can be carried out.
02
NT check can not be done after a while?
Changes in NT are directly related to gestational age, so the duration of examination is relatively fixed.
It is difficult to observe before 11 weeks and gradually disappears after 14 weeks, so the best time for NT testing is 11-13 weeks + 6 days of pregnancy. Fu Aijia warm reminder: The gestational week mentioned here refers to the gestational week calculated by the last menstrual period, not the gestational week calculated according to the fetal development in the early B ultrasound.
If you want to do NT tests for pregnant mommys, you can make an appointment now to avoid missing out
03
How to see the data in the NT report?
The more obvious the NT thickening, the higher the probability of fetal treasure abnormalities, and the degree of abnormality will become more and more serious. Usually, the thickness of NT can not > 3 mm, when > 3 mm, 10% will develop into an abnormal fetus; when the > 6 mm, the degree of abnormality is significantly increased, and 90% will develop into an abnormal fetus.
For example, NT examination is like a security check, and NT thickening is the "abnormal molecule" that needs to be further examined.
04
Is there a problem with the fetus with NT thickening?
Abnormal thickening of NT, the main reason is related to fetal chromosomal abnormalities, the more common are 21-trisomy, 18-trisomy, 13-trisomy syndrome, etc.; it may also be fetal structural malformations, such as heart, skeletal system development abnormalities, relative to chromosomal abnormalities, structural malformations or other reasons caused by NT thickening accounted for a relatively small proportion.
In addition, there are many fetal NT thickening can not find the cause, if the chromosomes of the fetal treasure are normal, the structure is also normal, the thickened NT will slowly disappear with the growth of gestational age, and gradually return to normal.
If the NT is outside the normal range, it does not mean that there must be a problem with the fetal treasure. When the examination finds that the fetal treasure NT is thickened, the expectant mother does not have to worry too much, cooperate with the doctor's examination, first rule out whether the fetal chromosomes and fetal structure are abnormal; if they are normal, the development of the baby after birth is the same as that of the normal baby with early pregnancy NT.
05
What should I do if I diagnose NT thickening by ultrasound?
Get the ultrasound results, found that the NT thickening, pregnant mothers must actively cooperate with the doctor to find out the cause of the thickening, and then carry out targeted treatment.
How to deal with it:
◆ When the NT value > normal value, the fetal chromosomal abnormalities are excluded by amniocentesis or non-invasive DNA;
◆ Do another ultrasound examination in 16-18 weeks to exclude the early structural abnormalities of the fetal treasure;
◆ When these abnormalities are excluded, they can be carried out according to the normal progress of obstetric examination.
Let your baby grow up healthy from an early age
It is the wish of every mom and dad
Fathers-to-be, remember at the right time
Accompany expectant mothers to do NT examinations
